Well first of all, I think Domijan has by far the most potential. Yeah his movement and backhand obviously need work, but his forehand is HUGE and he has the type of serve you expect for a guy of his size.
Only thing is, I've never seen him as very passionate and I'm not sure if we can be positive that he will fulfill all his potential.

As for Chase, he is a solid all-around player that I think should concentrate on clay, because it suits his game best. Having said that, I'm not sure if he will ever go out of his way to play red clay tournaments.

Tennys and Rhyne are both pretty talented baseliners that I think will have great results on American hardcourts.

To answer your question, I think Domijan should as long as he puts in the work.

Quite an impressive defeat from Benni
The change from grass to hard court could have played against him.
He did lose lo Levodskikh (outside the top 300) at Hertogenbosch too.
I'm sure that as soon as he gets used to playing in hard courts again he'll be getting
far in the tournaments
Good luck, Benni!... and congratulations to Sandgreen

I am not a specialist on US players but at least Sandgren already has done an impact on the futures tour, so he is the most likely to have success... now this win over Becker like Benji was some amateur...
